问题： dragObjp.innerHTML=Map.Read(zgid,dragObj.style.left,dragObj.style.top,image,imgid).value;

Question

问题：    dragObjp.innerHTML=Map.Read(zgid,dragObj.style.left,dragObj.style.top,image,imgid).value;
Map缺少对象    这个MAP来源于AjaxPro.2
我的作法为:
 1.      <httpHandlers>
        <!--javascript-->
        <add  verb="Post,Get" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro.2" />
      </httpHandlers>
 2.     在CS.中引用 [AjaxPro.AjaxNamespace("Map")] 
          protected void Page_Load(object sender, EventArgs e)
        {
            //这是AjaxPro2.dll引用的属性   注册吧
            AjaxPro.Utility.RegisterTypeForAjax(typeof(Map_View));}
3.      在CS文件中为:
        [AjaxPro.AjaxMethod]
        public string Read(string zgi_id, string left, string top, string image, int imageid)
        {
            string a = get_div_html(zgi_id,left,top,image,imageid);
            Console.WriteLine("{0}",a);
            return a;        }
4.     前台   <script language="javascript" src="JS/Map_View.js"></script>
         <img src="./images/zoom_in.gif" width="20" height="20" style="cursor: hand" onclick="bigit('<%=zgi_id%>','<%=zg_image%>')"
                            title="放大">5.     在JS文件中为:
        function bigit(zgid,image){            
if(imgid<5) 
{
imgid=imgid+1;
   var  dragObj=document.getElementById("block1");
   var  dragObjp=document.getElementById("block0");
    dragObj.parentNode.removeChild(dragObj);
    dragObjp.innerHTML=Map.Read(zgid,dragObj.style.left,dragObj.style.top,image,imgid).value;
}
else
{
alert("已经是最大展馆显示！！！");
}
}请问怎么解决呀??
